The CryoPower Cool Combustion process enables recovery of otherwise wasted exhaust heat which is then cooled via the injection of a small amount of liquid nitrogen. The liquid nitrogen acts as both a coolant and an additional source of energy, reducing emissions and improving fuel efficiency.
This game-changing technology offers unprecedentedly high efficiency and near-zero emissions - in some cases, actually cleaner than ambient air. Cryopower's extreme efficiency translates to a fuel economy improvement of 30%. The Cryopower concept focuses on a split-cycle combustion process; instead of refining existing four-stroke engine technology, the engine divides four strokes between two paired cylinders: one for intake/compression, and another for power/exhaust. Using isothermal compression to control temperature, this engine concept was originally conceived as a means of enabling otherwise unachievable improvements in fuel economy and reduced CO2, targeted at achieving at least 60% brake thermal efficiency, making it significantly more fuel efficient than current engine technology.
The early development work carried out on the test rig installed at the University of °ÅÀÖÊÓƵ not only validated the potential but also, crucially, demonstrated the highly impressive low-NOx emissions credentials of the CryoPower combustion process.
The technology is suitable for use with heavy duty engines running on diesel or a range of other liquid or gaseous conventional, bio- or synthetic fuels ranging from long-haul trucks, to stationary power, off-highway equipment, and self-powered and multi-mode railway traction.
